APPARATUS FOR CUTTING LARD OR THE LIKE.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed July 19, 1909. Serial No. 508,418.

To all whom it may concern:

Be it known that I, ANDEns JOHAN AL- FRID BERGMAN, a subject of the Kingof Sweden, and a resident of Varamo, Sweden, have invented certain newand useful Improvements in Apparatus for Cutting Lard or the Like; and Ido hereby declare the following to be a full, clear, and exact de:scription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings,

' and to figures of reference marked thereon,

which form a part of this specification.

My invention relates to machines for cutting lard and the like intostrips and cubes, and it has for its object to provide means forincreasing the cutting action of the knives by imparting a drawingaction thereto, substantially the same as that imparted to ahand-operated knife.

The invention consists of a series of stationary blades mounted in abase, and a series of cooperating movable blades mounted in a frameconnected with the base by means of pivoted supports adapted to impart acombined longitudinal and arcuate movement to the frame; together withmeans operated by the movement of the frame to automatically remove thecut material from the stationary blades.

One embodiment of the invention is illustrated in the accompanyingdrawing, wherein- Figure 1 is a side elevation, and Fig. 2 a plan viewof a complete machine.

In said drawing, 1 designates the base constructed in the form of atable provided with a rectangular opening 2. Mounted transversely acrossthe opening and near one end thereof are two bridge pieces, 3, 4, inwhich are fixed, by any preferred means, a series of parallel blades 5.These blades have their cutting edges directed upward, and directlyabove them or resting thereon near one end is fixed an abutment 6adapted to hold the material to be out against displacement. A secondseries ofblades, as 7, extend between and cooperate with the firstseries, said second series being mounted in a frame composed of two endmembers, 8, 9, which are connected by the side rods 10, 11. The endmember 9 lies under the blades 5, and is pivotally connected at each endwith one end of a rod 12, the other ends of the rods 12 being pivoted onbolts 13 mounted in the side walls at one end of the opening 2. Boltedto and projecting perpendicular to the base 1 on each side of saidopening 2 is a standard 14, and to the upper end of each standard ishinged at one end a rod 15, the other ends of the rods 15 being hingedto the ends of the end member 8. The rods 12 and 15 lie in parallelplanes and move in parallel relation to each other. It will thus be seenthat by means of the above-described mechanism a longitudinal andarcuate movement is imparted to the blades 7, substantially the same asthat imparted to a hand-operated knife in cutting, or in other words,the blades 7 are simultaneously moved in the direction of their lengthand in the direction of the length of the stationary blades 5.

Means are provided for automatically removing the lard from thestationary blades after it has been sliced. Such means comprise a shelf,16, preferably of the shape shown in Fig. 2, mounted at one corner on apivot 17, which projects upward from the base 1 at the side of theknives 5. The swinging of the shelf on the pivot is effected by means ofa collar 18 slidably mounted on the side rod 11 and connected with asleeve 19 slidably mounted on a fixed guiderod 20 which is mounted onthe base 1 paralled to the fixed blades 5, said sleeve being connectedwith the shelf by a link 21 pivotally connected to the sleeve near thefront end thereof and to the shelf at a point in rear of the pivot 17.As the movable frame carrying the blades 7 is pushed down by means of ahandle 22 fixed to the end member 8, the collar 18 on the rod 11 ismoved toward the handle, and with it the sleeve 19, causing the link 21to swing the shelf 16 on its pivot and over the backs of the blades 7,and under the lard on the blades 5. When the handle is raised, either byhand, spring, weight or the like, into the position shown in Fig. 1, theshelf with the lard thereon is, by the means above described,automatically swung back into the position shown in Fig. 2. If the nowsliced lard is to be cut into cubes, it is again placed in position onthe blades 5 and the operation repeated.

I claim 1. In an apparatus of the character described, a series ofcutting members and means to simultaneously impart a longitudinal andarcuate movement thereto.

2. An apparatus of the character described, comprising a stationarycutting member, a movable cutting me1nber, -sup.-.

pivoted supporting members for the frame mounted in parallel relation toeach other.

4-. In an apparatus of the character described, a series of fixedblades, a series of blades movable between the latter, a frame for themovable blades, rods pivoted to the frame, and means to support the rodsin parallel relation to each other,

' 5. In an apparatus of the character described, a series of fixedblades, a series of movable blades, means to support the latter inangular relation to the fixed blades, and means to move the latter inthe direction of their length and in the direction of the length of thefixed blades.

6. In an apparatus of the character described, a base, a series ofblades fixed thereon, a series of blades adapted to move between theblades of the fixed series, a frame for the movable blades,- a rodpivotally connected to the base and to the frame, a support on the base,and a rod pivotally connected to the support and to the frame inparallel relation to the aforesaid rod.

7. In an apparatus of the character described, a series of fixed blades,a series of movable blades, a frame for the latter, means to support theframe in angular relation to the fixed blades and to permit movement ofthe frame in a lateral and a longitudinal direction to the fixed blades,in combination with a swingingmember, and mechanism connecting the frameand swinging member to move the latter over the fixed and movable bladesf 17 v 8. In an apparatus of the character described, a base having anopening therein, a series of fixed blades mounted over the opening, aseries of blades movable between the blades of the fixed series, a framefor the movable blades mounted in angular relation to the base, a rodpivotally connected to the base and to the lower end ofthe frame, a

support on the base, a rod pivotally connected to the support and to thetop of the frame in parallel relation to the aforesaid rod, a shelfpivoted on the base, a slide mov able parallel to the fixed bladesoperable by the movement of the frame, and a linkconnecting the shelfand slide.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presenceof two subscribing witnesses.
